The duration of the buffs below are for a fully-ranked Charm. When the player receives a buff (apart from Rare Resource), a charm icon will appear to the top right corner of the HUD, it will also display for a brief time what kind of buff it is. You can also determine which buff is currently active is by looking at said buff's duration.

Warframe power costs are refunded on cast. (Channelled abilities refund the initial cast, the effect also refunds any channel cost during those 10 seconds.) This effect also applies to melee channel attacks.

The Orange critical hit chance buff sets critical chance to 200%, and on melee, it applies beforeBlood Rush. This means that using Blood Rush will cause the 200% critical hit chance to be multiplied with the combo counter, allowing the critical hit chance to scale up very quickly.

The Double Pickups and Affinity buff can proc and be followed by a Rare Resource buff, doubling the number of resources that are generated by the Smeeta Kavat.

Buffs are stackable, they do not overwrite the first buff. 2 times or more Doubled Pickup/Affinity is possible, and the buff is multiplicative (2x>4x>8x>16x>etc.).

Every 27s there is a 28% chance to receive a random buff out of 6 buffs, getting a Doubled Pickup Buff out of the 6 buff pool is 28% * 1/6 or 4.667%, getting the buff twice in a row is 0.217% (4.667% * 4.667%), the duration of each buff is 120s (or 156s with Tek Enhance ) which means at most 5 possible instances active at the same time, the chance of that is happening is 0.000022%, the probability becomes 99.999988% after 4,545,454 procs. or 122,727,258 seconds or 2,045,454.3 minutes or 34,090.905 hours or 1,420.45 days or 3.89 years.

With Doubled Pickup/Affinity, Affinity Pickups are 4x multiplied (Because both multipliers affect them). Double affinity only applies once (think of it as the final multiplier that is applied at the very end).

The Doubled Pickups bonuses can also increase the amount of Kuva or Void Traces rewarded, but only before the player receives them.

Sometimes, Warframe powers are unaffected by the critical chance buff.

While using Ivara and the Reload buff activates, the player can fire the Artemis Bow as if it had no draw time.

At random times the mod will stop working for the rest of the mission.

If your Smeeta dies while a buff is active, it is possible to have it permanently for the mission. (Infinite Insta Reload)

Due to the Orange critical hit chance buff setting your critical hit chance to 200%, weapons that have been modded with greater than 200% crit chance actually get reduced critical hit chance while the buff is active.

Fixed Smeeta's Charm ‘Doubled Pickups and Affinity’ buff not working as intended and doubling a number of things that were unintended. It now properly doubles pickups: Resource, Health, Energy, Affinity, Credit and Ammo (previously it would).

Changed Smeeta's Charm ability, specifically the Resource related Charm, to give a single Resource pickup rather than a random stack of resources that may not be the appropriate size for the chosen Resource type.
